Merge branch 'dev' into api-flash-string-progmem

- Revert variables templatable output_type back to None since variable
  lambdas can return any type (float, int, etc.), not just strings.
- Use lazy import identity check (output_type is std_string) instead of
  brittle string comparison in templatable().
- Clarify ESP8266 populate_service_map comment explaining why STATIC_STRING
  fast path is not needed (all codegen strings are FLASH_STRING on ESP8266).

-  // CRITICAL: NRVO (Named Return Value Optimization) - DO NOT REFACTOR WITHOUT UNDERSTANDING
-  // ===========================================================================================
-  //
-  // This function is carefully structured to enable NRVO. The compiler constructs `result`
-  // directly in the caller's stack frame, eliminating the move constructor call entirely.
-  //
-  // WITHOUT NRVO: Each return would trigger SerializationBuffer's move constructor, which
-  // must memcpy up to 768 bytes of stack buffer content. This happens on EVERY JSON
-  // serialization (sensor updates, web server responses, MQTT publishes, etc.).
-  //
-  // WITH NRVO: Zero memcpy, zero move constructor overhead. The buffer lives directly
-  // where the caller needs it.
-  //
-  // Requirements for NRVO to work:
-  //   1. Single named variable (`result`) returned from ALL paths
-  //   2. All paths must return the SAME variable (not different variables)
-  //   3. No std::move() on the return statement
-  //
-  // If you must modify this function:
-  //   - Keep a single `result` variable declared at the top
-  //   - All code paths must return `result` (not a different variable)
-  //   - Verify NRVO still works by checking the disassembly for move constructor calls
-  //   - Test: objdump -d -C firmware.elf | grep "SerializationBuffer.*SerializationBuffer"
-  //     Should show only destructor, NOT move constructor
-  //
-  // Why we avoid measureJson(): It instantiates DummyWriter templates adding ~1KB flash.
-  // Instead, try stack buffer first. 768 bytes covers 99.9% of JSON payloads (sensors ~200B,
-  // lights ~170B, climate ~700B). Only entities with 40+ options exceed this.
